I bought this projection lens from a relative of an old Zeiss Ikon worker from Kiel together with some other unmarked Zeiss Ikon prototype lenses. I’m not a 100% sure about the age, but Zeiss changed to Zeiss-Opton in the late 1940s I think.

The biggest difference from a normal Alinar 50/1.4 lens I can tell with this lens is that it’s coated, and the body is slightly different. The original Alinar design was patented by Zeiss in 1931. This lens, from what I could count is a 5 element in 3 groups lens, kind of Sonnar like.

Zeiss kept the Alinar trademark name after the war, but changed the optical design completely to something that looks very much like a Super-Kiptar lens from ISCO. Which makes sense because the original Alinar design was already outdated.

The lens almost cover full frame, and can be adapted to various mirrorless cameras. It has a lens barrel diameter of 42.5mm, which was a standard back then. So it’s easy to buy clamps for it and adapt it. What might be challenging is that this lens was designed as a short flange range lens. If you need any advice on how to adapt the lens, send me a message.

Condition:
Unfortunately there is some coating damage on the front element. There is no big scratches, there is no fungus or haze. Some internal dust is expected. Barrel is in good shape.

I don’t have any official payment method or store, but if you’re interested in buying or trading you can email me at espen.susort@gmail.com.
